Between getting a pixie cut and completing the New York City Marathon, Pamela Anderson's been a busy lady as of late!

She somehow made time to drop by The Ellen DeGeneres show, and in an episode of the show airing Thursday, Nov. 7, she explained the reason behind her drastic hair change and talked about finishing the 26.2 mile race.

"I did it," Pamela, 46, said of finishing the marathon. "And I stole your haircut!"

Ellen was flattered, then asked the mom of two if her new 'do was so she could "be more aerodynamic so you can run faster in the race."

"Absolutely, yes," Pam quipped. But the real reason for chopping off her locks? "I just thought my hair had a life, and I wanted to kind of put that behind me and start fresh," she said. "I thought it would be good for the marathon, and it was."

The Baywatch alum compared the last five miles of the marathon to giving birth—but the race was harder! "It was like giving birth and then being told to run as you're giving birth. It was so much pain in my hips," she said. "I don't know if women are meant to run especially after having kids, but we raised a lot of money for Haiti for our J/P [Sean Penn's Haitian Relief Organization]."

So it was worth it, although definitely tough—as evidenced by the photo Pam shared showing the race's painful aftermath. "The cutest bellboy poured me an ice bath at the hotel," she recalled. Ellen, of course, asked if said bellboy stayed in there with Pam, to which she replied, "No, unfortunately."

Ha. Ellen also admitted she was wrong for (jokingly) telling Pamela last month that she wouldn't complete the marathon. "Because I really want to apologize to you," she said, presenting Pam with a shirt that said "Ellen Is Not Always Right"—only, as you can see, the "not" is pretty tiny.
